Abstract (en)

[origin: US2008299459A1] The ions other than a lithium ion and having a greater ion radius is interposed, before the lithium ion is doped, as an interlayer securing member in a vanadium oxide having a layered crystal into which the lithium ion can be doped. Since the interlayer securing member is interposed, the dope or dedope of the lithium ion into or from the vanadium oxide afterward can smoothly be performed. A sodium ion or the like can be employed as the interlayer securing member.
